Markowitz Efficient Set A set of portfolios with returns that are maximized for a given level of risk based on mean-variance portfolio construction. The efficient "solution set" to a given set of mean-variance parameters (a given riskless asset and a given risky basket of assets) can be graphed into what is called the Markowitz efficient frontier. Investopedia Says: The Markowitz efficient set is all of the portfolios on the efficient frontier, or those that generate the largest return for a given risk level. The mean-variance and subsequent efficient set theory at one time revolutionized portfolio management, and remains a core lecture in any economist's university years. The theory of mean-variance portfolios lead to the capital asset pricing model, and is still a vital component of professional money management today.
